It's because ffp3 is a European standard. They're terrible to wear though. I'm glad COVID is over and I only ever wore the absolute minimum required. Only got it once during the mask mandate and that's when I didn't actually wear it in a crowded bar (nobody did so there was no point). I only sniffled for 2 days anyway.

>They're terrible to wear though. I'm glad I went "full nerd" early and got a PAPR pollution mask.[1] I estimate I'm getting essentially the same 99% protection, except without the hot stuffy sensation. The CO2 increase is real, despite propaganda to the contrary. This isn't because a mask "blocks oxygen" (duh), it's just because you're re-inhaling a larger volume of exhaled air, beyond the normal mouth/nose+trachea+…

I am surprised how bad people are at basic arithmetic! A N99 face mask is 5 times better than a N95 one, not just 4% better! So, I wonder why FFP3 is only available in Europe. I buy the FFP3 face masks, which are manufactured in Poland, fr…

Doesn’t every additional infection also reduce the likelihood of you getting it again or even noticing you got it as it gets milder? If I hadn't tested I would not have guessed that the mild cold I just got was my second covid infection. My first covid infection was quite bad even with 3 vaccinations.
